PUMPING MEANS' 'FOR GAS APPARATUS.

Specification of Letters Patent.

Patented Mar. 14, 1916.y

Application led February 4, 1915. Serial No. 6,125.

To all 'whom 'it may concern:

Beit known that I, CARSON BELDIN, a citizen of the United States, and a resident of Berlin, in the county of Worcester and State of Maryland, have invented certain new and useful Improvements in Pumping Means for Gas Apparatus; and I do hereby declare the following to be a full, clear, and Y exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in gas apparatus and more particularly to such as is adaptable for use in generating and regulating carbureted air for lighting and heating purposes.

One object of the invention is to provide a simple and efficient apparatus for generating and controlling thesupply of gas for domestic use, the plant being such as can be installed in rural districts or places beyond the reach of city gas supply systems. p

With this and other objects in view, the invention consists in certain novel features of construction and combinations f parts as hereinafter set forth and pointed out in the claims.

The Vaccompanying drawing is a view partly .in section, illustrating my improvements.

1 represents a tank which may be conveniently supported upon legs 42, and within said tank 1 and concentric therewith, another tank 3 is located,-said tanks being spaced apart to form a water chamber4 4 betweenfthem.

Located centrally within the tank 3, isa pump cylinder, the lower end of which is provided with a pipe 6 secured to and passing through the bottom 7, while said pump cylinder is supported in an upright position by braces 8 extending therefrom to the wall of the tank3. A piston 9 is closely fitted within the cylinder 5 so as to have watertight contactwith the'wall thereof, and to this piston, a piston rod 10 is secured.. The piston rod 10 passes through a suitable stuiiingbox at the upper endof. the cylinder and atits upper end, it is secured to the top 1l of an inverted cylinder or bell 12, the vertical wall of which latter dips into the water chamber 4 between the tanks 1 and 3.

A pipe 13 (which receives water under pressure from any convenient source of supply)vcommunicates with the pipe 6 tosupply pump cylinder under the piston therein. A short tube 14 is secured to and passes through the bottom 7 so as to communicate at its upper end with the air chamber 15 formed within the tank 3 and the bell 12, the lower end of said tube being open. The admission of air to the chamber 15 is controlled by a counterweighted valve 16v mounted within said chamber and adapted to seat upon the upper end of the tube 14.

A pipe 17 communicates with the lower portion ofthe air chamber 15 and extends to and communicates with a suitable carbureter 18,-a check valve being located in the circuit of this pipe as indicated at 19. At a suitable point in this pipe, near the carbureter, an air vent 20 is provided. *l

A pipe 21 communicates with the carbureter and is provided with a capped inlet 22 for gasolenefor charging thecarbureter.

This pipe also constitutes the outlet for carbureted air and with it, one end of a pipe 23 is connected, the other end of said pipe 2,3-

being connected with a mixer 24 of suitable construction. A gas supply pipe 25 communi- Cates with the mixer'for conducting the gas tothe point or points of consumption. f To y provide ready means for supplying air to be mixed with the gas vcoming from the car-1 bureter, a pipe 26 is connected at one end with the air pipe 17 Vand at the other end with the inlet end of the mixer. A counterweighted valve 27 is provided in the mixerA for automatically controlling the admission of air to the mixerthrough the pipe 26.

A pipe 28 communicates with the upper I end of the pump cylinder 5, and has con- -nectcd thereto, by means of a coupling 29, a `pipe 30, which latter extends downwardly through the bottom 7 Vof the apparatus. A

` pipe 31 is connected, through a coupling 32,

with the pipe 30, and said pipe 31 is connected with apipe 33. One end of the pipe ,33l is connected with the pipe 17 at a point` 55 water under pressure to the lower end of the beyond the check valve 19 and the other end 1 of said pipe 33 is made with an air inlet controlled by a check valve 34. A check valve 35 is also located in the pipe 33 between the connections of said pipes with the pipes 17 and 30.

A valve 36 is located in the water pipe13 and the casing of this Valveis'provide'dwith' a discharge outlet 37 to permitVv the discharge of water from the pump cylinder when the valve 36 is closed during .the descending moifemeiit of the piston. The rodnl of the valve 36 is connectedfwih. af pinion)` 38 in such manner that rotation of the latter willi effect the opening or closing of the* valve. Ax racky bar 39 mesheswiththe pinion'l 38 andv is' carried by a rod 40 movable iin guides 41.- Springs 42 are mountedv on the'y rodfy40f and each is connectedf at? one end toV said rod. A rod 43 is carried by and-movable with the bell 12 and this rodl isl pro videdy at itsllower end wit-h an= arm m0vableo'n the rod 40 between the springs on` the latter;

WhentheY valve 36is open, water, under pressure;L will? enter the lower end of the cylinder and force the piston 9r upwardly,

thus raising the bell 12an`d causingftheil'l ing of the air chamber throughfthe valfved inlet tube 14. At the same time,v the' air `in the cylinder 5' above the piston w-ill-be'forcedl out-'through the pipes 28430-31 and 33 toI the air pipe lj'f and thence to-thefca'rbureter.- Means are thus provided for effecting the continuity' of the air supply' toi the carbukk reter'while theair chamber 15` istil-ling with airduring the" rising movementl of the" bell 122 Zhen the bell 12reac'hes'theI upper end off' the airpassing from the chamber 15"-A out* throughfthefpipe 17 to the'Y carburet'er. DuriAA ing'` the descent of" the piston 9,. air will" bel drawn into the; pumpv cylinder throughi the check valve" 34, andy pipes 31-3028`fthe check valve 35 being, at this time, closed?.

/Vhen" the bellLV reaches the lower end of its movement",y thearni 44 will engage thelowerA spring 42 on rodl 40 andca'useI a downward movement of' said rod` which. willeffecttlie openiiigof thevalve 36' inA the water pipe', as will-be readily understood. Power willno'wA be again supplied for raising the pump pisd tony 9 andthe bellJ 12' and the cycle'" of'o'peraJ-J tions above described will' be repeated?V In order to' prevent the water in the cliari'i"A be provided. This coil may be inclosed in a casing 46 containing a suitable heating l burner 47', and said coil is connected at itsrespective ends with the water chamber 4. A spigot 48A may be connected with the waterchamber, for discharging the `water therefrom when desired. l

Variou'sch'ange'smight be made in the de'-v tails otk construction, of my invention1 without Vdeparting from the spirit thereof or limitingits scope, and hence I dol-notk wish hereinY seti brtlil Y ,7 5 to restrict myself` to the precise details- Having fully describedv my inventioni.
